SOLVED. (I hope!)

These are the steps:

remove everything that has something to do with the graphics enviroment, as it says here:

Then,

$ sudo gedit /etc/default/grub

and change this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

for this one:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset acpi_backlight=vendor"

then

$ sudo update-grub

reboot and be happy. Desktop effects work too.
